The gorgeous gray-shingled mansion at 3 West End Road, East Hampton, better known as Grey Gardens, has hit the market for $19.95 million.

The home, previously occupied by Jackie Kennedy relatives "Big Edie" and "Little Edie" Bouvier Beale, was made famous in the 1975 documentary film, "Grey Gardens," which uncovered the pair's shocking living conditions.

Plagued by limited funds, the mother and daughter retreated into isolation and resided for decades in the once-handsome home that fell into a state of disrepair and decay, infested by fleas, inhabited by numerous cats and raccoons, deprived of running water and filled with garbage. Health inspectors even reported spotting human waste in the upstairs bedrooms.

"Little Edie" sold the house in 1979 after her mother's death for $220,000 ($726,000 today) to current owners Sally Quinn and Ben Bradlee, who restored the dilapidated home, maintaining the original gray shingle color -- a Hamptons signature.

Despite keeping the original structure of the home, there is hardly any trace of the mansion's former condition.

Featuring seven bedrooms and six and a half baths, the home oozes grandeur with tasteful touches that invoke its storied history, like warm hardwood floors, a terracotta-tiled sunroom and Tudor-style diamond-paned bay windows.

In addition to a Har-Tru tennis court and heated swimming pool, a quaint stucco cottage sits on the property's lush (yet manicured) two-acre grounds.

Pleasant Hill Library in Hastings is lined up to get remodeled as part of Dakota Countys ongoing push to update its libraries.

The countys 2017 budget includes $2.8 million for improvements to the Hastings library, which has not been renovated since it opened in 1994.

For a number of years, Pleasant Hill was functioning at an adequate level and other needs at other branches became more pressing, said Margaret Stone, director of Dakota County Library, which operates nine libraries.

Now, county officials are focusing on getting Pleasant Hill up to speed with more modern amenities and possibly more space, Stone said.

More private work areas for patrons, a larger meeting room for group events and more backroom space for staff are high priorities, she said.

The small meeting room is by far the biggest issue, she said.

A consulting firm hired by the county recently completed a comprehensive needs assessment and submitted a space plan, three schematic designs and an estimated budget. The study will be the focus of an informational open house for residents from 5 to 7 p.m. Thursday at the library, 1490 South Frontage Road.

Dakota County has recently been aggressively expanding and remodeling its libraries. Its long-range facilities plan recommends renovations on a 12- to 15-year cycle to adjust program space to meet changing needs.

Wescott Library in Eagan was renovated in 2009, followed by Burnhaven in Burnsville in 2010, Farmington Library in 2013 and Inver Glen in Inver Grove Heights in 2014.

Work on a $5.4 million remodel of Galaxie Library in Apple Valley will start this fall and include a multipurpose lab at the buildings entrance; a consolidated staff area with a relocated drive-up book drop; and an educational play area for children.

Originally built in 1990 as part of thecountys Western Service Center, Galaxie Library underwent minor remodeling in 2004.

Meanwhile, a needs assessment for Heritage Library in Lakeville will be completed this year.

Two of the remodeling designs for Pleasant Hill include an addition to the building, Stone said.

We need to have better work spaces for people who bring in their own devices, she said. Our wireless use is growing through the roof.

A recommended remodeling option could go before the county board for approval in mid-March, she said.

When it comes to visitors, Pleasant Hill has the third-lowest gate count among the countys libraries.Last year, 143,000 people visited the library, which hosted nearly 300 programs.

By comparison,Galaxie, the countys busiest location, had a gate count of more than 312,000.

Because of its location, Pleasant Hill pulls in residents from rural townships south of Hastings as well as southern Washington County residents, Stone said.

Discount grocer Aldi will spend $1.6 billion to remodel and expand more than 1,300 of its 1,600 U.S. stores in the next few years, including making more room for fresh and organic produce, as well as dairy, bakery and meat sections, the retailer said Wednesday.

Aldi, whose U.S. operations are based in Batavia, is also in the midst of spending $3 billion on land, facilities and equipment to open, as previously announced, an additional 650 locations nationwide. Last year, for example, it entered the Southern California market.

The store renovations, which also will include more airy ceilings, natural lighting and environmentally friendly building materials, are expected to occur by 2020.

Aldi, which operates in 35 states and has more than 24,000 workers, has about 150 stores in the Chicago area. A location in Plainfield is the first store to be remodeled in the Chicago area. The new store layout will grow from an average of 10,000 square feet of selling space to 12,000 square feet.

Aldi didn't immediately have an answer about how many of the new stores would be in the Chicago area or in what suburbs or neighborhoods.

Known for its no-frills stores, Aldi said shoppers won't see higher prices as a result of the company spending billions on remodeled and new stores.

Aldi's private-label brand accounts for about 90 percent of a store's inventory, which allows it to keep its prices low and enables shoppers to spring for pricier products in the store, the company said.

Grocery shoppers have become more finicky, increasingly reaching for food they believe is natural and fresh, generally trading up for quality and down for staples. Natural and gourmet-type stores have flourished, as have discounters. To beat back competition, traditional grocers, including Jewel-Osco, have overhauled their offerings, particularly at the perimeter of the store where customers hunt for fresh produce, meat and prepared foods.

Aldi said it has added several new product lines that in recent years have become popular, including gluten-free and organic foods and a line of premium baby items. It said it also has made such product improvements as removing synthetic colors and partially hydrogenated oils from Aldi-brand foods.

Aldi last year joined other chains that have replaced junk food with healthier options as the call for healthier food intensifies. Its Chicago-area stores said a year ago that they would stock "healthier" fare, including nuts, trail mixes, dried fruits and granola bars, near checkout lines instead of candy. Candy will still be available elsewhere in the store.

House Siding Kansas City MO | Replacement Windows

By Reuben Saltzman In Masonry Veneer, Stone Siding On September 4, 2012

Without a doubt, the sexiest new siding being used on the front of houses is stone siding. I say stone siding because thats what everyone calls it, but what Im really referring to is Masonry Veneer. This is a man-made product thats meant to look like stone siding, and is installed in a similar manner to stucco.

While masonry veneer looks great, its susceptible to the same moisture problems that stucco is. Moisture testing experts in the Twin Cities agree that this product has experienced the exact same type of moisture intrusion problems asstucco. Building science expert Dr. Joseph Lstiburek actually calls this product lumpy stucco, because thats essentially what it is.

While newer stucco installations are done quite well, the folks installing masonry veneer seem to have a lot of catching up to do on proper installation details. When I inspect masonry veneer, I use the Masonry Veneer Manufacturers Associations installation guide, which you can find here MVMA installation guide. This guide is packed with diagrams showing how to install the material, based on generally accepted methods.

I find the same installation shortcomings over and over. To help illustrate these issues, Ive taken several installation diagrams from MVMAs guide and edited them down to more clearly illustrate where the installations went wrong. As a home inspector, I dont get to see all the different layers of materials that get installed behind the masonry veneer; my inspection is limited to what I can see on the surface, and thats what I report on. To make the installation diagrams easier to understand, Ive removed the labels of all the components thatarentvisible during the course of a home inspection.

Masonry veneer should be kept at least 2 above hard surfaces, such as concrete, and 4 above the soil.

When the material is buried in dirt, water can wick up in to the material and cause rotting at the wall.

There should also be a 2 gap to paving, but this is rarely done especially on columns.

Of course, leaving a 4 gap at the ground isnt the prettiest looking thing in the world, but there is a solution; simply have the weep screed terminated at least 4 above the ground, and have another layer of masonry veneer installed below it, as shown in the diagram below.

The photo below shows this detail done properly.

Heres a close up note the weep screed.

When masonry veneer has a vertical transition to something like wood trim, windows, or other siding materials, it should have a 3/8 gap left between the two different materials. This gap needs to have a foam backer rod pushed behind it, and then filled with sealant to help prevent water intrusion. This is rarely done.

Masonry veneer needs to be kept 2 above roof surfaces to help prevent water from wicking up in to the wall. The photo below shows a common deviation, where the masonry veneer actually touches the shingles. This is just asking for trouble.

Dryer vents, kitchen exhaust vents, bath fan vents, and other similar vent terminals should be pushed up against a bed of sealant, but theyre often buried in masonry. What happens when the vent cover gets broken and needs to be replaced?

Just like dryer vents, exterior sillcocks (aka faucets or hose bibs) need to be embedded in sealant on the surface of the masonry veneer, not buried behind the veneer. What happens when the faucet needs to be replaced?

How many bloody knuckles will this installation cause?

The nice thing about the installation shown above is that they got the vertical transition correct check out that thick bead of caulk.

Of course, this is only a partial list of the things that can go wrong on a masonry veneer installation. If youre planning to have this material installed on your home, make sure the MVMAs installation instructions are followed to help lower the potential for water intrusion. If youre buying a home with masonry veneer already installed, treat it the same way you would stucco consider having invasive moisture testing done.

Install Roofing in Charlotte NC at Affordable Cost - Satellite PR News (press release)

Updated: Feb 8, 2017 - 11:51 AM

LACEY, Wash. - A fire has gutted a warehouse at a roofing company in Lacey.

The owner of MadsenRoofing said a passerby saw flames on the roof of the business on Martin Way andHohStreet Northeast at 3 a.m. Wednesday and called the business office to say there was a fire.

Three fire departments responded to fight the flames.

The owner said the warehouse is a total loss but he is thankful that the office space next door and some mobile equipment survived.

He said the outpouring of support from people in the roofing community has been overwhelming and that he is thankful that no one was hurt.

A Lacey fire spokesperson said the fire was especially tough to fight because of the roofing materials inside the warehouse. Flames could still be seen as late as 8:30 a.m.

The owner said he wants to get the business open again by Monday. Eighteen employees work at the company.

An investigation into the cause of the fire will start once the building is deemed safe to enter.

The building was secured when firefighters arrived, so at this point, the fire is not believed to be suspicious.

All matter breaks down over time. The structures that surround us today are no exception to that law of physics. Some building materials are more durable than others, like stone and steel, but unfortunately the days of structures surviving thousands of years, like the Egyptian pyramids and Roman cathedrals, is over. Preventive maintenance of building exteriors is more important than ever.

Every building or structure should have a preventive maintenance program in place for its exterior components, says Mark Sheehan of Western Specialty Contractors Facades Division, a national specialty contractor based in St. Louis, MO. How extensive the program needs to be will depend directly on the size of the building, number of different materials and components, geographic location, and personnel available to keep it updated.

A preventive maintenance program consists of two major partsthe inspection and the execution. During inspection, some of the more complex structures may require special access and assistance from a contractor. However, for most structures, an in-house maintenance crewwith a little bit of trainingis capable of doing the job.

When performing the inspection, it is extremely important to document the findings and keep them in a consistent format from year to year. It is also necessary to inspect any work that has recently been performed as those repairs may still be under warranty, says Sheehan. Specific items to inspect and document include the following.

Gutters, drains, downspouts, drainage, roof. Decaying leaves, pine needles, and dirt runoff can all contribute to ponding water and clogged gutters and downspouts. It is essential that all roof drains remain clear of obstructions. In addition to risk of water pouring into the occupied spaces should a breach in the roof occur, freezing and thawing of ponding water during the fall and winter months can cause extensive roof damage.

Perimeters of doors, windows, and other wall penetrators. The exterior walls of a building can be a significant source of water leakage. Many openings are required in commercial building walls for plumbing, irrigation connections, lighting, HVAC system elements, exhaust vents, air intakes, joints around windows and doors, and fire alarms, to name a few. Unplanned holes may also be present caused by aging brick joints that need re-pointing, vanishing sealants, damage from acid rain and settling cracks.

Building control and expansion joints. Like any other element of a structure, its controls and expansion joints can become damaged. Evidence of damage includes warping, cracking, leaking water, loosening screws and building settlement or moving.

Walking/driving surfaces. When water infiltrates concrete, it can freeze, causing the water to occupy 9% more volume than in its liquid state. This expansion causes distress on the concrete, which can lead to fractures that will continue to grow exponentially as saturation of the material increases. Cracks, spalls, rust spots, deterioration, potholes and heaves are all signs of damage.

Copings and flashings. When surveying the roof, be sure to inspect the copings and flashings. Water damage to exterior and interior walls can be significant if these elements are not maintained properly.

The second part of any preventive maintenance program is the execution. The data collected during the inspection should be put into a budget for needed repairs. It is also important to evaluate the need for protective measures such as scalers or coatings. A specialty contractor with experience in facade maintenance and restoration can itemize each inspection item and offer specific recommendations for repairs.

If you are in charge of a structure that does not have a preventive maintenance program in place for its exterior, you should think about implementing one immediately, says Sheehan. Preventive maintenance keeps the building off of the deferred maintenance path, which usually results in exponential restoration costs.

Preventive Maintenance For Roofing And Exteriors - Facility Executive Magazine

By John B. Letts From The February 2017 Issue

When facility executives are faced with the important decision of selecting roofing insulation for a project, there are several critical factors that must be considered. Specifiers and contractors can certainly provide valuable insight, but its just as beneficial for facility executives to be knowledgeable about both types of insulation before making a decision. After all, insulation plays a crucial role in minimizing energy costs and making an impact on a buildings carbon footprint. Roofing insulation should not only meet building codes, but also offer the most value related to performance and durability. Each insulation option brings its own distinct benefits to a commercial roofing project.

Due to its components, mineral wool goes by many names, including mineral fiber, rock wool, slag wool, and stone wool insulation. Slag wool is more commonly used, and accounts for about 80% of the mineral wool industry. Mineral wool originated in Germany in 1871 and was one of the first insulation materials to be commercially produced. To manufacture mineral wool, molten glass, stone, or slag and other raw materials are heated and spun into very thin fibers, much like how cotton candy is spun. When the material is produced, binders are used to hold the fibers together and form it to meet specific product needs. Mineral wool is commonly available as blanket and loose-fill insulation.

Polyisocyanurate, more commonly referred to as polyiso insulation or ISO, is a closed-cell rigid foam board used in more than 70% of commercial roof construction. Polyiso was originally developed in the 1930s and was once used as insulation for beer barrels. Since then, it has evolved to become an environmentally friendly roofing and wall insulation solution. The boards, which are typically 4 x 8, are sandwiched between a top and bottom facer.

When selecting insulation, comparing and contrasting factors like fire protection, R-value, and compressive strength must be considered. Heres how polyiso insulation matches up to mineral wool in key categories:

Fire Protection. Thanks to its flame retardant chemicals, mineral wool is highly fireproof, which makes it a popular choice for commercial buildings where fire performance is the most critical factor. Mineral wool is composed of noncombustible batts, or precut sections of insulation, made up of inorganic fibers that have an impressive melting point of more than 1,000F.

Polyiso insulation also has outstanding fire performancepolyiso is a thermoset material and isnt susceptible to melting. Building owners and facility managers need insulation that can stand up to the heat without deteriorating over time.

Thermal Performance and Weight. Mineral wool is more often found in walls than in roofs because of its weight, and has a relatively low R-value of 3.8. Mineral wool insulation is 4.5 times heavier than polyiso and requires twice as many boards to be installed, which can increase project costs. However, that density means that mineral wool boasts better sound control properties than polyiso.

Polyiso offers the highest R-value per inch of any rigid foam board insulation. This means it resists the flow of heat and keeps the interior of a building warm or cool, depending on the season, helping to keep energy costs low. Polyiso insulation typically has an R-value ranging from R-5.6 to R-8 per inch, which is 45% more than mineral wool insulation. As gas escapes, however, the R-value of polyiso can drop over time, but foil and plastic facings can help stabilize that number.

Compressive Strength. Here, compressive strength is directly related to durability and is defined as the ability of a rigid foam board to maintain its shape when force is applied. Mineral wool may be thick insulation, but its compressive strength is only 11 pounds per square inch (psi). This means that factors like mechanical fasteners, foot traffic, vibrations, and other external pressures can cause significant damage to the insulation. When mineral wool is stepped on, it does not fully recover back to its original state, which can result in reduced thermal performance.

Polyiso insulation has significantly higher compressive strength than mineral wool and can range from 16 psi to 25 psi. This ensures it will maintain its shape despite foot traffic and routine maintenance to the roof, making polyiso a durable choice.

Materials and Environmental Impact. Some sustainability experts have expressed concerns regarding the binder that ties the fibers of mineral wool together. Typically, the binder is a phenol formaldehyde or urea-extended phenol formaldehyde, an element that poses a potential health concern and may be harmful to air quality.

Although mineral wool is typically made from 70% recycled content, unlike polyiso, it cannot be recycled and re-used on reroofing applications. It requires approximately 85% more energy to produce than polyiso and has a global warming potential (GWP) that is 3.5 times higher.

The facers used in polyiso insulation are made up of cellulosic material with 15% chopped fiberglass and recycled material. According to the Polyisocyanurate Insulation Manufacturers Association (PIMA), the energy savings potential of polyiso insulation over a typical 60-year building life span is equal to up to 47 times the initial energy required to produce, transport, and install it. These factors, along with polyisos zero ozone depletion potential; its opportunity for reuse; and its lower GWP compared to mineral wool, make polyiso an eco-friendly insulation option.

Polyiso is equipped with shorter fasteners as well as thin, light boards. It therefore requires fewer insulation pallets than mineral wool. This has less environmental impact and can significantly reduce costs associated with labor, handling, and crane fees.

While both mineral wool and polyiso insulation offer their own distinct properties, selecting which one to use can depend largely on the specific roofing project.

Letts primary experience is in polyisocyanurate insulation board and its performance in roof and wall systems.
